Prevalence of multidimensional frailty and pre-frailty in older people in different settings: A systematic review and meta-analysis

Systematic review and meta-analysis of the prevalence of frailty and pre-frailty amongst older hospital inpatients in low- and middle-income countries

BACKGROUND

As populations age, low- and middle-income countries (LMICs) are rapidly adapting hospital services to meet the needs of older populations. This systematic review aimed to establish the prevalence of frailty and pre-frailty amongst older people admitted to hospital in LMICs, and to compare levels with existing estimates for high-income settings.

METHODS

Databases Medline, Embase, CINAHL and PsychInfo were searched, and results were manually screened by two researchers. Included studies were cross-sectional or cohort design and reported data from hospital inpatients, aged ≥60 years, in LMICs, using validated methods for identifying frailty. Risk of bias was assessed by two researchers using the Joanna Briggs Institute checklist. Where possible, results were synthesised using meta-analysis.

RESULTS

Twenty-nine studies were included, all reporting data from middle-income countries. Physical frailty tools were the most common, with Fried's phenotype and the FRAIL Scale being the most often used methods of assessment. The pooled estimate of the prevalence of frailty was 39.1% [95% confidence interval (CI) 31.9-46.6%] comprising data from 23 311 older inpatients. For pre-frailty, prevalence was 40.0% (95% CI 25.1-51.4%) from 6954 individuals.

DISCUSSION

Due to the paucity of eligible studies and their geographical distribution, these pooled estimates are only representative of the burden of frailty in select middle-income settings (particularly China). Future research should seek to establish the prevalence of frailty in hospitals in low-income countries, and to assess clinical outcomes by frailty status, in order to develop bespoke clinical tools and to aid the planning of future geriatric services.

A randomized controlled trial to assess the efficacy of standardized tai chi in prefrail older adults with immunosenescence: design and protocol

BACKGROUND

Frailty is a common geriatric syndrome worldwide, and its early identification and intervention have important clinical significance. Resistance training has been recommended as an efficient means to combat loss of muscle strength and mass; however, it is often not a prioritized option for older adults. Tai chi is a well-known traditional Chinese exercise that has a beneficial impact on physical performance, balance ability, metabolism, and immune function.

AIMS

With the newly emerged concept of muscle-immune homeostasis, this study focused on determining the efficacy of tai chi prefrail older adults who develop immunosenescence. Furthermore, the proper timing of the exercise regimen for maximizing the therapeutic effect of tai chi has also been explored.

METHODS

This 12-week, multicenter, randomized controlled trial (RCT) was conducted with participants between 60 and 75 years of age. A total of 144 prefrail participants were included in this study and were randomized (1:1:1:1) to four groups: (1) a control group with only health education, (2) a morning tai chi group, (3) a morning resistance training group, and (4) an afternoon tai chi group. The primary endpoints included physical performance, frailty index scores, muscle strength, and mass, and the secondary endpoints were the sarcopenia quality of life score, Berg balance scale score, bioenergetic anti-stress index (BASI), and immune risk profile (IRP). The data were analyzed according to the intention-to-treat protocol.

DISCUSSION

The results of this investigation aided in determining whether tai chi effectively reversed the prefrail state of older adults and ameliorated biomarkers of immunosenescence. Furthermore, proper exercise timing was also determined to maximize the efficacy of physical training.

The association between use of proton pump inhibitors and frailty index among middle-aged and older adults

AIMS

This study aimed to investigate the association between use of proton pump inhibitors (PPI) and frailty index (FI), and to assess the causality relationship using Mendelian randomization (MR).

METHODS

A total of 9756 middle-aged and older adults from the National Health and Nutrition Examination Survey were included. The FI was evaluated using a previously validated 49-item deficit model to assess frailty status, which is one of the common approaches to measure overall health burden. We performed weighted multivariable-adjusted linear regression to assess the association between PPI use and FI, and conducted a two-sample MR to evaluate causality, employing various sensitivity analyses for robustness. The inverse variance weighted (IVW) method was used as the primary analysis.

RESULTS

Multiple linear regression analysis revealed a positive association between PPI use and FI (β = 0.048, 95% confidence interval [CI]: 0.042-0.054, P < .001). This association was observed in both short-term (≤ 1 year) and long-term (> 1 year) PPI users (P for trend < 0.001). The MR study also revealed a positive association between PPI use and FI based on the IVW method (β = 1.183, 95% CI: 0.474-1.892, P = .001).

CONCLUSIONS

While our findings suggest a potential link between PPI use and FI, they should be interpreted with caution due to the study's limitations. Although the MR analysis suggests a causal relationship, further research, particularly longitudinal studies, is needed to confirm these findings and better establish temporality.

Comparison of robustness, resilience and intrinsic capacity including prediction of long-term adverse health outcomes: The KORA-Age study

BACKGROUND

Frailty, resilience and intrinsic capacity (IC) are concepts to evaluate older person`s health status, but no comparison of their associations with adverse health outcomes exists. We therefore aimed to assess which concept is most useful for determining long-term health of older adults.

METHODS

Analyses were based on the KORA (Cooperative Health Research in the Region of Augsburg)-Age study (n = 940, 65-93 years). Frailty was evaluated using the physical frailty-phenotype by Fried et al. For comparability to resilience and IC, we chose the protective concept of robustness instead of frailty in the present analysis. Resilience was measured by the 11-item resilience-scale. The IC-score was based on 4 domains (locomotion, cognition, vitality and psychiatric capacities). Associations with falls, disability, and hospitalization at 3-year and 7-year follow-up and with mortality were evaluated by multivariable adjusted logistic and Cox regression. Concept overlaps were illustrated by a Venn-diagram.

RESULTS

In the fully adjusted models, robustness showed significant inverse associations with most outcomes (3-year follow-up: OR (95%CI): disability 0.448 (0.300-0.668), 7-year follow-up: falls 0.477 (0.298-0.764), hospitalization 0.547 (0.349-0.856), and all-cause mortality 0.649 (0.460-0.915)) while resilience and IC showed significant inverse associations with disability only (e.g., 7-year-follow-up: resilience: 0.467 (0.304-0.716), IC: 0.510 (0.329-0.793)). 23% of the participants met the criteria for both robustness and IC while 22% met those for robustness and resilience.

CONCLUSION

Robustness was the most useful concept, showing the strongest protective associations for most adverse health outcomes. IC and resilience showed their main strengths in capturing protective associations for disabilities. Robustness overlapped with resilience and IC, supporting the concept of mind-body-interaction.

SANTANA Cohort: Study on Frailty in Institutionalised Older Adults and Its Relationship With Gordon's Functional Health Patterns

AIM

This study investigated whether Gordon's Functional Health Patterns (FHPs) can predict frailty in older adults residing in nursing homes over 5 years.

DESIGN

Prospective cohort study with participants from 10 nursing homes across five countries.

METHODS

Researchers assessed 1245 participants at baseline and 903 at follow-up (5 years) using standardised frailty measures and FHP assessments. Statistical analyses explored the relationships between FHPs and frailty.

RESULTS

FHPs, particularly those related to mobility, nutrition and social interaction, significantly predicted lower frailty risk at baseline. Furthermore, FHPs showed an increased ability to predict frailty over time, explaining a substantial portion of frailty variation at both baseline and follow-up. Analyses also revealed differences in how specific FHPs impacted frailty, suggesting the importance of individual functional variations.

CONCLUSION

This study suggests that Gordon's FHPs are a valuable tool for predicting frailty in older adults within institutional settings. Integrating FHPs into clinical practice can promote early frailty detection and intervention. Future research should explore how FHPs change over time and their impact on frailty in broader populations.

REPORTING METHOD

The study followed the CONSORT guideline for cohort studies to enhance the quality and transparency of reporting the results.

Association of visceral adiposity index and lipid accumulation product with frailty in U.S. adults: a cross-sectional study from NHANES

BACKGROUND

Frailty poses a considerable public health challenge because of its association with negative health consequences. Although obesity is recognized as a contributor to frailty, conventional measures fail to adequately account for the effects of visceral adiposity. The study aimed to investigate the associations between the visceral adiposity index (VAI) or lipid accumulation product (LAP) and frailty.

METHODS

This study used data from the National Health and Nutrition Examination Survey (NHANES), which included 5,279 participants aged ≥ 20 years. The VAI and LAP were calculated via recognized formulas, and frailty was evaluated via a deficit accumulation approach. We employed logistic regression and restricted cubic splines to assess the associations among LAP, VAI and frailty.

RESULTS

Out of 5,279 participants, 1,836 individuals were categorized as frail. According to the fully adjusted models, the highest VAI and LAP values were significantly associated with frailty, with adjusted ORs of 1.84 (95% CI: 1.40-2.42) and 2.47 (95% CI: 1.89-3.24), respectively, compared with the lowest values. A nonlinear relationship was identified between the LAP and frailty, with an inflection point of 1.589 (ln-transformed), whereas the VAI was linearly associated with frailty. Sensitivity analyses confirmed the robustness of these associations.

CONCLUSION

The VAI and LAP are significantly related to frailty, highlighting the importance of visceral adiposity in frailty risk. These results increase the understanding of the metabolic underpinnings of frailty and may guide the development of targeted prevention strategies.

Genetic prediction of serum micronutrient levels and the risk of frailty: Evidence from a Mendelian randomization study

Although observational studies have revealed a link between frailty and serum micronutrient levels, it remains unclear whether these 2 states are directly connected. Thus, Mendelian randomization (MR) was used to investigate the causal relationship between frailty and blood micronutrient levels. Summary-level data for 15 blood micronutrients (copper, selenium, zinc, calcium, iron, magnesium, potassium, folate, carotene, vitamin A, vitamin B6, vitamin B12, vitamin C, vitamin D, and vitamin E) were obtained from people of European ancestry from the Integrative Epidemiology Unit. Single nucleotide polymorphisms associated with the frailty index were extracted from a published meta-analysis study in the UK Biobank and Swedish TwinGene. We used the inverse variance weighted (IVW) method for the primary analysis. We employed pleiotropy residual sum and outlier (MR-PRESSO) tests, MR-Egger intercepts, Cochran Q tests, and leave-one-out analysis to assess causality validity and robustness. Reverse MR analysis was used to determine reverse causation. The IVW results revealed that vitamin D (odds ratio [OR] = 1.096; 95% confidence interval [CI]: 1.019-1.178; P = .014) increased the likelihood of a high risk of frailty, whereas the frailty index had a protective effect on selenium (OR = 0.622; 95% CI: 0.396-0.977; P = .039), carotene (OR = 0.916; 95% CI: 0.858-0.979; P = .009), vitamin C (OR = 0.895; 95% CI: 0.837-0.957; P = .001), iron (OR = 0.921; 95% CI: 0.859-0.988; P = .022), and vitamin E (OR = 0.907; 95% CI: 0.847-0.971; P = .005). The reverse IVW analysis revealed no significant correlation between micronutrient levels and frailty indices. The study revealed causal links between vitamin D and the risk of frailty. Notably, our findings highlight the necessity of adjuvant vitamin D in frailty management.

A simplified multidimensional scale approach is effective in predicting mortality in hospitalized older adults and highlights the role of nutrition

BACKGROUND & AIMS

Malnutrition and cognitive impairment are among the major contributors to frailty, that significantly increases the risk of mortality of older hospitalized patients. Multidimensional frailty assessment tools, such as the multidimensional prognostic index-MPI, a tool based on a standard comprehensive geriatric assessment (CGA), have proven valuable for predicting adverse outcomes, including mortality of older adults following acute illness but its application in everyday clinical practice is limited. We hypothesized that removing parameters not closely associated with mortality and sorting the patient population according to the presence or not of cognitive impairment with possible integration of common laboratory markers, could provide a simplified approach that could improve practicability in all settings with at least comparable 1-year mortality predictive value.

METHODS

A retrospective cohort study was conducted in patients consecutively admitted to the Geriatric Clinic of the Maggiore University Hospital in Trieste, Italy from January 1st 2018 to December 31st 2019. Their demographics, functional, clinical, laboratory parameters and 1-year mortality were recorded. In a development cohort of 1032 consecutive patients, best predictors of mortality were selected via systematic analysis and included in simplified prognostic models and algorithms and subsequently compared for prediction of 1-year mortality. The predictive relevance of the best algorithms was then validated, in comparison to MPI, in a separate cohort of 575 consecutive patients.

RESULTS

While all demographic and tested laboratory parameters as well as MPI domains correlated with 1-year mortality, exclusion from MPI calculation of Short Portable Mental Status Questionnaire (SPSMQ), Exton Smith scale (ESS) and Mini Nutritional Assessment (MNA) significantly reduced MPI mortality predictivity, suggesting that not all MPI domains have the same weight. Further analysis showed that in the whole study cohort and in subgroups according to cognitive function, selected models including up to 3 parameters were superior to MPI in predicting 1-year mortality. In particular, models including MNA and albumin, or Exton Smith scale proved to better predict mortality in patients without or with severe cognitive impairment, respectively. A derived diagnostic algorithm applying different models according to cognitive status showed improved predictive value compared to MPI while requiring shorter estimated assessment time. Internal validation confirmed these results [HR: 4.37 (3.02-6.31) vs 3.16 (2.18-4.61), p < 0.0001].

CONCLUSIONS

In older acutely ill patients, a simplified multidimensional algorithm approach based on the assessment of cognitive function followed by nutritional status with the addition of plasma albumin or of functional status in patients without or with severe cognitive impairment respectively, may significantly improve 1-year mortality prediction while reducing assessment time. Moreover, these results highlight the prognostic value of MNA in association with albumin for 1-year mortality risk screening in the hospital setting and, for the first time, demonstrate its differential performance according to the presence or not of cognitive impairment.

Comparing How Three Frailty Scales Predict Negative Outcomes in Trauma Patients With Rib Fractures

INTRODUCTION

Frailty is a risk factor for adverse outcomes after injury. Herein, we compared three frailty scales: the Canadian Study of Health and Aging clinical frailty scale, the rib fracture frailty index (RFFI) and the modified frailty index-5, to assess which scale is most applicable in predicting risk for negative outcomes in older patients with rib fractures.

METHODS

Patients ≥65 admitted for rib fractures were retrospectively scored for frailty using the RFFI, Canadian Study of Health and Aging clinical frailty scale, and modified frailty index-5. Outcomes examined were in-hospital mortality, pneumonia, in-hospital intubation, hospital length of stay, and discharge to skilled nursing facilities. Areas under the curve, sensitivity, specificity, negative predictive value, and positive predictive value were determined for each frailty scale with each outcome. Agreement was determined using Fleiss' Kappa. P <0.05 was considered significant.

RESULTS

Three hundred forty-one patients were included. All three scales demonstrated similar predictive abilities for the measured outcomes. RFFI predicted mortality and pneumonia 70% of the time. All three scales predicted discharge to skilled nursing facilities 60% of the time. The concordance for all three frailty scales was 241/341 (70.7%). Fleiss Kappa was 0.40 [0.34-0.46] (P < 0.001), indicating a fair to moderate agreement. The predictive ability of all three scales was higher in patients 65-74 y old than in patients ≥75.

CONCLUSIONS

Overall, no scale appeared to significantly outperform the others by areas under the curve estimation. Interrater reliability was higher in the 65 to 74-y-old population compared to the 75 and older population.

Significance of frailty in mortality and complication after hepatectomy for patients with liver cancer: a systematic review and meta-analysis

BACKGROUND

Frailty has been associated with increased mortality and complications among liver cancer patients. However, the frailty prevalence and outcomes in frail populations with primary liver cancer have not been systematically validated.

METHODS

Embase, PubMed, Scopus, and Web of Science were searched for eligible studies that explored the prevalence and impact of frailty in liver cancers from inception until October 26, 2023. The pooled prevalence, hazard ratio (HR), and odds ratio (OR) corresponding to 95 % confidence intervals (CI) in mortality and major complication estimates were conducted.

RESULTS

A total of 18 studies containing 38,157 primary liver cancer patients were included. The prevalence of frailty in liver cancer was 35 % (95 % CI = 25-46; p = 0.000). Frailty was associated with an increased hazard ratio for 30-day mortality (HR = 7.03; 95 % CI = 0.71-69.45; p = 0.97) and 90-day mortality (HR = 4.59; 95 % CI = 1.76-11.95; p = 0.38). Furthermore, frailty was associated with an increased odds ratio for major complications in liver cancer patients (OR = 4.01; 95 % CI = 2.25-7.14; p = 0.49).

CONCLUSION

Frailty is frequent in liver cancer patients and may predict adverse outcomes in primary liver cancer patients with hepatectomy. Our findings highlight the importance of frailty assessment in this population.

Technological monitoring of motor parameters to assess multidimensional frailty of older people in the PRO-HOME project

An interconnected system employing Kinect Azure and Fitbit Sense for continuous and non-intrusive data collection was used in the PRO-HOME protected discharge program, aiming at monitoring functional and clinical parameters in hospitalized older patients at different risks of frailty. The present study shows the findings on 30 older patients included in the PRO-HOME project. The Fitbit Sense recorded the mean daily and hourly number of steps, mean daily walked distance, and time spent inactive. Moreover, Kinect infrared camera captured gait speed and daily mean latero-lateral (body sway) and antero-posterior oscillations (lean-in). Patients underwent a standard Comprehensive Geriatric Assessment (CGA) to compute the Multidimensional Prognostic Index (MPI), including basic and instrumental activities of daily living (ADL, IADL), cognition (Short Portable Mental Status Questionnaire, SPMSQ) and nutrition, risk of pressure sores (Exton-Smith Scale, ESS), comorbidity, number of drugs and cohabitation status. Significant correlations between the mean hourly number of steps and MPI (p = 0.022), IADL (p = 0.013), SPMSQ (p = 0.006), ESS (p = 0.009), and both mean and maximum automated gait speed (p = 0.046 and p = 0.048) were found. Automated gait speed was also correlated with mean walked distance per day (p = 0.007) and lean-in (p = 0.047). Domotic technological monitoring through Fitbit Sense and Kinect Azure provides information on multidimensional frailty, including mobility and cognitive and functional status, in older people.

Retrospective, propensity score--matched study examining the relationship between frailty and Clostridioides difficile infection in a national cohort of US veterans

BACKGROUND

Frailty is often more predictive of disease and mortality compared with chronological age. This study determined the impact of frailty on Clostridioides difficile infection (CDI) risk and outcomes in a national veteran population.

METHODS

This was a retrospective cohort study of CDI and control veteran inpatients and outpatients from fiscal year 2003 to 2018. Baseline frailty was presented as the Veterans Affairs (VA) Frailty Index. Propensity score--matched analyses were conducted to compare CDI risk, CDI health outcomes, and 1-year new-onset frailty-associated conditions.

RESULTS

A total of 11,451 CDI and 11,451 matched control patients were included. Baseline frailty conditions were more common among CDI patients, especially involuntary weight loss (6.0% vs 3.4%, P < .001) and anemia (24.6% vs 18.7%, P < .001). VA Frailty Index was significantly higher for CDI patients (0.13 vs 0.11, P = .019). Frail CDI patients were more likely to experience 30-day mortality (11.3% vs 1.1%, P < .001) and 60-day CDI recurrence (20.4% vs 16.3%, P < .001) compared with non-/prefrail CDI patients. At 1year, CDI patients were significantly more likely to be categorized as frail (19.6% vs 17.0%, P < .001).

CONCLUSIONS

This study demonstrated the potential association between frailty and CDI risk and health outcomes, as well as new-onset frailty diagnoses in patients who develop CDI.

Genetic insights into the causal linkage between systemic inflammatory regulators and frailty

OBJECTIVES

Previous studies have suggested the associations between systemic inflammation and the risk of frailty, but causal relationships between them remain not well established. We conducted a bi-directional Mendelian randomization (MR) analysis to investigate the causal links between systemic inflammatory regulators and frailty.

METHODS

Genetic variants associated with systemic inflammatory regulators were obtained from a comprehensive genetic study on 41 circulating cytokines, such as interleukin-4 (IL-4), eotaxin, and macrophage inflammatory protein-1β (MIP1β). We integrated summary-level data on frailty from two independent genetic studies on frailty index (FI) and Fried frailty score (FFS). The inverse-variance weighted method was used to assess the causal estimate. Sensitivity and heterogeneity analysis was performed to evaluate the stability of the estimates. The false discovery rate (FDR) method was used for P value adjustment of multiple comparisons.

RESULTS

Genetically elevated levels of MIP1β and decreased levels of eotaxin were suggestively associated with increased FI (MIP1β: β = 0.016, Praw = 0.006, PFDR = 0.083; eotaxin: β = -0.030, Praw = 0.007, PFDR = 0.083) and FFS (MIP1β: β = 0.008, Praw = 0.027, PFDR = 0.247; eotaxin: β = -0.015, Praw = 0.014, PFDR = 0.247). In contrast, genetically predicted FI was suggestively associated with decreased levels of IL-4 (β = -0.395, Praw = 0.040, PFDR = 0.638) and platelet-derived growth factor BB (PDGF-BB, β = -0.385, Praw = 0.047, PFDR = 0.638) and increased levels of stem cell factor (SCF, β = 0.527, Praw = 0.005, PFDR = 0.204). Similar results were obtained from different sensitivity analysis.

CONCLUSIONS

The present study demonstrates that increased MIP-1β levels and decreased eotaxin levels might lead to a higher risk of frailty, whereas frailty might reduce the levels of IL-4 and PDGF-BB and increase the levels of SCF.

Identifying and Estimating Frailty Phenotypes by Vocal Biomarkers: Cross-Sectional Study

BACKGROUND

Researchers have developed a variety of indices to assess frailty. Recent research indicates that the human voice reflects frailty status. Frailty phenotypes are seldom discussed in the literature on the aging voice.

OBJECTIVE

This study aims to examine potential phenotypes of frail older adults and determine their correlation with vocal biomarkers.

METHODS

Participants aged ≥60 years who visited the geriatric outpatient clinic of a teaching hospital in central Taiwan between 2020 and 2021 were recruited. We identified 4 frailty phenotypes: energy-based frailty, sarcopenia-based frailty, hybrid-based frailty-energy, and hybrid-based frailty-sarcopenia. Participants were asked to pronounce a sustained vowel "/a/" for approximately 1 second. The speech signals were digitized and analyzed. Four voice parameters-the average number of zero crossings (A1), variations in local peaks and valleys (A2), variations in first and second formant frequencies (A3), and spectral energy ratio (A4)-were used for analyzing changes in voice. Logistic regression was used to elucidate the prediction model.

RESULTS

Among 277 older adults, an increase in A1 values was associated with a lower likelihood of energy-based frailty (odds ratio [OR] 0.81, 95% CI 0.68-0.96), whereas an increase in A2 values resulted in a higher likelihood of sarcopenia-based frailty (OR 1.34, 95% CI 1.18-1.52). Respondents with larger A3 and A4 values had a higher likelihood of hybrid-based frailty-sarcopenia (OR 1.03, 95% CI 1.002-1.06) and hybrid-based frailty-energy (OR 1.43, 95% CI 1.02-2.01), respectively.

CONCLUSIONS

Vocal biomarkers might be potentially useful in estimating frailty phenotypes. Clinicians can use 2 crucial acoustic parameters, namely A1 and A2, to diagnose a frailty phenotype that is associated with insufficient energy or reduced muscle function. The assessment of A3 and A4 involves a complex frailty phenotype.

Risk factors for falls in older people with pre-frailty: A systematic review and meta-analysis

BACKGROUND

Frailty is considered highly prevalent among the elderly, and falls are a severe adverse event that occurs at a significantly higher rate in frail elderly patients, leading to serious consequences. The pre-frailty stage represents a reversible transitional state between health and frailty, and targeted interventions for pre-frail older adults can effectively reduce the incidence of falls in this population. Existing studies have not definitely identified the risk factors for falls in pre-frail older adults. This paper explores the relevant risk factors for falls in pre-frail older adults.

METHODS

PubMed, Embase, Web of Science, Cochrane Library, CBM, CNKI, Wan fang, and VIP databases were searched for studies published from inception to 2023, without language restrictions. Observational studies were included in this systematic review that analyzed risk factors for accidental falls in pre-frail older adults. The NOS scale was used to evaluate the quality of cohort studies and case-control studies, while the AHRQ scale was used to evaluate the quality of the cross-sectional study. We utilized odds ratios (OR) and their corresponding 95 % confidence intervals (CI) to describe the statistical indicators. OR and 95 % CI values were directly extracted and organized in Excel. In cases where OR and CI values were not directly available, we extracted β and p values, calculated Exp using functions, and subsequently derived OR and 95 % CI using formulas. Finally, data pertaining to each risk factor were incorporated into RevMan 5.4 software for statistical analysis and effect size synthesis. We performed tests for heterogeneity and evaluated publication bias.

RESULTS

A total of 14,370 studies were initially identified, and 26 studies were included in the systematic review. Among these studies, 14 were of high quality, while the remaining 12 were of moderate quality. A total of 16 risk factors were identified as potential risk factors for falls in pre-frail older adults. Significant risk factors were peripheral neuropathy(OR = 3.18, 95 %CI:3.02-3.35), decreased gait speed(OR = 1.90, 95 %CI:1.60-2.27), decreased ability to perform activities of daily living(OR = 1.57, 95 % CI:1.42-1.75), grip strength decreases(OR = 1.53, 95 % CI:1.17-2.00), gender (female)(OR = 1.51, 95 % CI:1.39-1.64), pain(OR = 1.47, 95 %CI:1.41-1.54), history of falls(OR = 1.20, 95 %CI:1.13-1.28) and age(OR = 1.10, 95 %CI:1.07-1.14).

CONCLUSIONS

The occurrence of falls in pre-frail older adults is associated with multiple risk factors. These risk factors can provide clinical nursing staff with specific focal points for monitoring this population and devising targeted fall prevention measures, with the aim of reducing the incidence of falls in pre-frail older adults.

Sarcopenia and frailty among older Chinese adults: Findings from the CHARLS study

BACKGROUND

Sarcopenia and frailty are common among elderly individuals and present substantial health hazards. Exploring their relationship is essential for optimizing geriatric healthcare, particularly within the context of China.

METHODS

A population-based cross-sectional design was employed using data from the China Health and Retirement Longitudinal Study (CHARLS). The study enrolled 5,714 participants aged ≥60 years who underwent assessment for sarcopenia following the criteria established by the Asia Working Group for Sarcopenia (AWGS 2019) in 2019. Frailty status was determined using a frailty index that categorized participants into robustness, pre-frailty, and frailty stages. Multivariable logistic regression models were employed to examine the relationship between sarcopenia and frailty and pre-frailty conditions. Subgroup and interaction analyses were performed to explore the robustness of the associations between sarcopenia and frailty across different subgroups.

RESULTS

Among the participants, 1,028 (18.0%) were identified as frailty, 2,987 (52.3%) as pre-frailty, and 645 (11.3%) had sarcopenia. Sarcopenia demonstrated an independent association with higher risks of frailty (OR = 2.13, 95% CI: 1.52-2.99) and pre-frailty (OR = 1.42, 95% CI: 1.20-1.81) in the multivariable logistic analysis. Subgroup and interaction analyses consistently demonstrated significant associations across nearly all demographic and health-related subgroups.

CONCLUSIONS

This study highlights that sarcopenia is significantly and independently associated with frailty and pre-frailty among older adults in China. Early detection and targeted interventions for sarcopenia are crucial to mitigate frailty and its adverse health outcomes in aging populations, emphasizing the need for tailored healthcare strategies to promote healthy aging.

Feasibility and Effectiveness of a 12-Week Concurrent Exercise Training on Physical Performance, Muscular Strength, and Myokines in Frail Individuals Living in Nursing Homes: A Cluster Randomized Crossover Trial

OBJECTIVE

To examine the feasibility and effects of a 12-week exercise intervention on physical performance, muscular strength, and circulating myokines in frail individuals living in nursing homes.

DESIGN

A cluster randomized, 2-period, 2-intervention crossover trial.

SETTING AND PARTICIPANTS

Frail residents of 9 nursing homes were randomly assigned to either 12 weeks of concurrent exercise training (n = 5, 29 participants) or usual care (n = 4, 17 participants). The concurrent exercise training consisted of resistance and aerobic exercises (3 days/week). The usual care consisted of everyday routine and standard care. After a 4-week washout period, participants crossed to the other intervention.

METHODS

The feasibility outcomes included recruitment rate, dropout rate and reasons, harms during the trial, adherence to exercise, and implementation cost. The primary endpoint was the change in physical performance measured by the Short Physical Performance Battery (SPPB). The secondary endpoints were changes in muscular strength (eg, handgrip strength, isokinetic knee extension, and flexion strength) and serum myokines concentration (myostatin and decorin).

RESULTS

From the 46 participants enrolled (aged 70-99 years, 67.4% female), 34 completed the trial (26.1% dropout rate), the median adherence was 93.75%, and no adverse events occurred during the exercise sessions. The concurrent exercise training provided significant benefits over usual care on SPPB (B = 2.18; 95% CI, 1.35-3.00; P < .001), handgrip strength (B = 2.15; 95% CI, 1.00-3.30; P < .001), myostatin concentrations (B = -7.07; 95% CI, -13.48 to -0.66; P = .031) and myostatin-decorin ratio (B = -95.54; 95% CI, -158.30 to -32.78, P = .004). No significant between-group differences were found for the remaining secondary endpoints.

CONCLUSIONS AND IMPLICATIONS

This concurrent exercise training is feasible, well-tolerated, and effective in improving physical performance, handgrip strength, myostatin, and myostatin-decorin ratio concentrations in frail older adults residing in nursing homes. These data reinforce the relevance of integrating exercise interventions in long-term care settings.

Frailty as a predictor of adverse outcomes in patients with gastric cancer: A systematic review and meta-analysis of 75,357 patients

BACKGROUND

Frailty is the most problematic expression of population ageing, which has been associated with increased mortality and complications among patients with gastric cancer (GC). However, previous evidence about the frailty prevalence and outcomes in frail populations with gastric cancer remains unknown.

METHODS

Eligible studies were searched in Embase, PubMed, Scopus, and Web of Science to explore the prevalence and impact of frailty in patients with gastric cancer from inception until November 25, 2023. The pooled prevalence of frailty, hazard ratio (HR), and odds ratio (OR) corresponding 95 % confidence intervals (CI) in mortality and postoperative complications estimates were analyzed.

RESULTS

A total of 24 studies containing 75,357 GC patients were involved. The prevalence of frailty in gastric cancer was 27 % (95 % CI = 24-30; I2 = 96.7 %; p = 0.000). Frailty was independently associated with an increased hazard ratio for mortality (adjusted HR = 2.14; 95 % CI = 1.60-2.86; I2 = 67.3 %, p = 0.000). Furthermore, frailty was significantly associated with an increased odds ratio for postoperative complication in GC patients (adjusted OR = 2.65; 95 % CI = 2.17-3.25; I2 = 0.0 %, Cochran's Q = 1.20, p = 0.878).

CONCLUSION

The prevalence of frailty in gastric cancer is common and has a significant adverse effect on GC patients' outcomes. Our findings highlight the importance of routine frailty assessment in GC patients, which may provide prognostic outcomes.

The relationship between insomnia and multidimensional frailty in community-dwelling older adults: A systematic review

OBJECTIVE

To examine the relationship between insomnia and multidimensional frailty among community-dwelling older adults.

METHOD

We conducted a comprehensive search in the Pubmed, Web of Science, and Embase databases up to May 15, 2024. The included cross-sectional studies were using the Joanna Briggs Institute's Evidence-Based Health Care Center's checklist for analytical cross-sectional studies; the longitudinal study used the Newcastle-Ottawa Scale for risk of bias assessment.

RESULTS

Out of 1571 studies, 14 were selected. The results indicate a positive relationship between insomnia and cognitive frailty, social frailty, and psychological frailty in community-dwelling older adults. However, the relationship between insomnia and total or physical frailty is unclear.

CONCLUSION

This study made an association between insomnia and cognitive frailty, social frailty, and psychological frailty in community-dwelling older adults. Due to the limited quality and quantity of the included studies, more high-quality cohort studies are required to verify the above conclusion.

The combined effects of heatwaves, air pollution and greenery on the risk of frailty: a national cohort study

The associations between heatwaves and frailty, as well as the joint effects of heatwaves with air pollution and greenery, are currently unknown. This study leverages data from the China Health and Retirement Longitudinal Study (CHARLS), which collected information from 6,400 older adults between 2011 and 2018. Our outcome variable was frailty, as measured by the frailty index (FI > 0.21). Heatwaves were defined based on maximum temperature, incorporating four thresholds (≥ 97.5%, 97.5%, 92.5%, and 90%) and three durations (≥ 2, 3, and 4 days). These variables were considered as time-varying variables, representing the one-year exposure preceding survival events. Fine particulate matter (PM2.5) and greenery (normalized difference vegetation index (NDVI)) were utilized as indicators of air pollution and greenery exposure, respectively, and were treated as time-varying indicators concurrent with heatwaves.Time-varying Cox proportional hazards models were employed to assess the independent effects, as well as the multiplicative and additive interactions of heatwaves, air pollution, and greenery on the risk of frailty. These effects were quantified using hazard ratios (HRs), a traditional product term representing the ratio of HRs, and the relative excess risk due to interaction (RERI). Our findings indicate that heatwaves are associated with an increased risk of frailty, with HRs ranging from 1.035 (95% CI: 1.006-1.064) to 1.063 (95% CI: 1.028-1.101). We observed both a positive multiplicative interaction (HRs > 1) and an additive interaction (RERI > 0) between high level PM2.5 concentration, lack of greenery, and heatwaves. This study reveals that the combined effects exacerbate the adverse impact of heatwaves on the risk of frailty. Moreover, the combined effects of heatwaves, air pollution, and greenery exposure on frailty risk vary across age, gender, and educational attainment.

Geriatric Syndromes Frequently (Co)-Occur in Geriatric Rehabilitation Inpatients: Restoring Health of Acutely Unwell Adults (RESORT) and Enhancing Muscle Power in Geriatric Rehabilitation (EMPOWER-GR)

OBJECTIVE

To determine the prevalence and co-occurrence of common geriatric syndromes in geriatric rehabilitation inpatients.

DESIGN

Restoring Health of Acutely Unwell Adults (RESORT) and Enhancing Muscle Power in Geriatric Rehabilitation (EMPOWER-GR) are observational, longitudinal cohorts.

SETTING

Geriatric rehabilitation.

PARTICIPANTS

Geriatric rehabilitation inpatients (N=1890 and N=200).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Geriatric syndromes included polypharmacy, multimorbidity (Cumulative Illness Rating Scale), cognitive impairment, depression (Hospital Anxiety and Depression Scale/Geriatric Depression Scale), malnutrition (Global Leadership Initiative on Malnutrition), functional limitation (Katz index), falls, physical frailty (Fried), and sarcopenia (European Working Group on Sarcopenia in Older People 2).

RESULTS

Inpatients in RESORT (R) (N=1890, 56% females) had a median age of 83.4 years (interquartile range [IQR], 77.6-88.4) and in EMPOWER-GR (E) (N=200, 57% females) of 79.8 years (IQR, 75.0-85.9). Polypharmacy (R, 82.2%; E, 84.0%), multimorbidity (R, 90.4%; E, 85.5%), functional limitation (R, 96.0%; E, 76.5%), and frailty (R, 91.8%; E, 92.2%) were most prevalent. Most inpatients had ≥5 geriatric syndromes at admission in both cohorts (R, 70.0%; E, 72.4%); few inpatients had only 1 (R, 0.4%; E, 1.5%) or no geriatric syndrome (R, 0.2%; E, 0.0%). Geriatric syndromes did not occur in isolation (without other syndromes), except for multimorbidity (R, 1%; E, 5%), functional limitation (R, 3%; E, 2%), falls (R, 0%; E, 4%), and frailty (R, 2%; E, 5%), which occurred in isolation in some inpatients; sarcopenia did not.

CONCLUSIONS

Geriatric syndromes are highly prevalent at admission to geriatric rehabilitation, with a median of 5 co-occurring syndromes. Implications for diagnosis and intervention potential should be further addressed.

Multidimensional frailty as a predictor of mortality among older adults: a systematic review and meta-analysis

OBJECTIVE

This systematic review examined studies that assessed the relationship between mortality risk and multidimensional frailty. The pooled risk of mortality was estimated via a meta-analysis.

DESIGN

A systematic review and meta-analysis.

METHODS

A systematic search for potentially eligible literature was conducted on January 2, 2023, using five electronic databases: Web of Science, CINAHL, PubMed, the Cochrane Library and Embase. This review included cohort or longitudinal studies examining the association between multidimensional frailty/prefrailty and mortality in older adults. The quality of the included studies was evaluated via the Quality in Prognosis Studies (QUIPS) tool. Two independent researchers identified eligible studies and extracted the data. The data analyses were performed via STATA, version 15.0.

RESULTS

A total of 24 studies with 34,664 participants were included. The 24 studies were published between 2012 and 2022, with most studies being performed in Italy (n = 16). The sample sizes of the included studies ranged from 71 to 12,020. Most included studies were conducted in hospital settings. The QUIPS bias assessment results showed that the most frequent source of potential bias was study confounding. The meta-analysis results showed that multidimensional frailty was a significant predictor of mortality (HR = 5.48, 95% CI = 3.91-7.67, p < 0.001). In addition, multidimensional prefrailty was also a significant predictor of mortality (HR = 2.56, 95% CI = 2.17-3.02, p < 0.001). The results of the meta-analysis using the ORs revealed that multidimensional frailty was a risk factor for mortality in older people (OR = 4.59, 95% CI = 2.47-8.55, p < 0.05).

CONCLUSIONS AND IMPLICATIONS

This systematic review of the relationship between multidimensional frailty and mortality found that multidimensional frailty/prefrailty is a predictor of mortality. More studies should be conducted in community dwelling populations and nursing homes.

Genetically predicted frailty index and risk of chronic kidney disease

Previous findings have reported the association between frailty and chronic kidney disease. However, the causality remains ambiguous. This study aimed to determine whether frailty index is causally associated with chronic kidney disease. We obtained the frailty genome-wide association study (GWAS) data and chronic kidney disease GWAS data from the FinnGen R5 (total n = 216,743; case = 3902, control = 212,841) as the exposure and outcome, respectively. A two-sample Mendelian randomization (MR) analysis was primarily conducted using the inverse-variance weighted (IVW), weighted median and MR-Egger regression analyses. Multivariable MR analysis (MVMR) was conducted for additional adjustment. In the two-sample Mendelian randomization analyses, a total of 14 single nucleotide polymorphisms (SNPs) were recognized as effective instrumental variables. The IVW method showed evidence to support a causal association between frailty index and chronic kidney disease (beta = 1.270; 95% CI 0.608 to 1.931; P < 0.001). MR-Egger revealed a causal association between frailty index and chronic kidney disease (beta = 3.612; 95% CI 0.805 to 6.419; P = 0.027). MR-Egger regression revealed that directional pleiotropy was unlikely to be biasing the result (intercept =  - 0.053; P = 0.119). The weighted median approach and weighted mode method also demonstrated a causal association between frailty index and chronic kidney disease (beta = 1.148; 95% CI 0.278 to 2.019; P = 0.011; beta = 2.194; 95% CI 0.598 to 3.790; P = 0.018). Cochran's Q test and the funnel plot indicated no directional pleiotropy. MVMR analysis revealed that the causal association between frailty index and chronic kidney disease remained after adjusting for potential confounders, body-mass index, inflammatory bowel disease, waist-hip ratio, and C-reactive protein. Our study provides evidence of causal association between frailty and chronic kidney disease from genetic perspectives.

A multicomponent personalized prevention program in the primary care setting: a randomized clinical trial in older people with noncommunicable chronic diseases (Primacare_P3 study)

BACKGROUND

Multicomponent interventions based on a comprehensive geriatric assessment (CGA) could promote active aging and improve health status in older people with Noncommunicable Chronic Diseases (NCDs), but conflicting evidences are available.

AIM

To evaluate the efficacy of a CGA-based multicomponent personalized preventive program (PPP) in reducing unplanned hospitalization rates during 12-month follow-up in community-dwelling older people with NCDs.

MATERIALS AND METHODS

In this randomized clinical trial (RCT), 1216 older adults recruited by 33 general practitioners (GPs) will be randomly allocated to intervention group (IG) or usual care control group (CG). The IG will receive a multicomponent PPP developed on the findings of the CGA-based Multidimensional Prognostic Index short-form (Brief-MPI), including structured interventions to improve functional, physical, cognitive, and nutritional status, to monitor NCDs and vaccinations, and to prevent social isolation. Participants in the CG will receive usual care. Brief-MPI, resilience, and health-related quality of life will be assessed after 6 and 12 months. Moreover, saliva samples will be collected at baseline in IG to measure biomarkers of oxidative stress, inflammatory cytokines, and oral microbiome.

EXPECTED RESULTS

The CGA-based PPP might reduce unplanned hospitalization rates and potentially institutionalization rates, emergency department (ED) and unplanned GP visits, and mortality. Further outcomes explored in the IG will be the adherence to PPP, resilience, health-related quality of life, and multidimensional frailty as assessed by the Brief-MPI.

CONCLUSIONS

Results will suggest whether the CGA-based multicomponent PPP is able to improve specific outcomes in a primary care setting.

Factors associated with frailty in older people: an umbrella review

BACKGROUND

The number of frail older people is increasing worldwide, and all countries will be confronted with their growing needs for healthcare and social support. The aim of this umbrella review was to summarize the evidence on the factors associated with frailty in older people, using a socioecological approach.

METHODS

PubMed (MEDLINE), Scopus, Web of Science, ScienceDirect, Hinari (research4life), and the Trip database were systematically searched up to April 2023. Systematic reviews of observational studies that explored factors associated with frailty in older adults aged 60 years and over were considered for inclusion. No language, geographical or setting restrictions were applied. However, we excluded systematic reviews that investigated frailty factors in the context of specific diseases. The Joanna Briggs Institute Critical Appraisal Checklist for Systematic Reviews and Research Syntheses and the ROBIS tool were used to assess the quality and risk of bias in the included studies.

RESULTS

Forty-four systematic reviews were included, covering 1,150 primary studies with approximately 2,687,911 participants overall. Several risk factors, protective factors and biomarkers were found to be associated with frailty, especially in community-dwelling older people, including 67 significant associations from meta-analyses. The certainty of the evidence was rated as moderate or reached moderate levels for seven factors relevant to older people. These factors include depression (OR 4.66, 95% CI 4.07 to 5.34), loneliness (OR 3.51, 95% CI 2.70 to 4.56), limitations in activities of daily living (OR 2.59, 95% CI 1.71 to 3.48), risk of malnutrition (OR 3.52, 95% CI 2.96 to 4.17), Dietary Inflammatory Index score (OR 1.24, 95% CI 1.16 to 1.33), maximal walking speed (Standardized Mean Difference (SMD) -0.97, 95% CI -1.25 to -0.68), and self-reported masticatory dysfunction (OR 1.83, 95% CI 1.55 to 2.18). Additionally, only greater adherence to a Mediterranean diet showed a high level of evidence (OR 0.44, 95% CI 0.31 to 0.64).

CONCLUSIONS

This umbrella review will provide guidance for prevention strategies and clinical practice by promoting healthy lifestyles and addressing all modifiable risk factors associated with frailty. Future systematic reviews should consider heterogeneity and publication bias, as these were the main reasons for downgrading the level of evidence in our review.

Efficacy of a Comprehensive and Personalised Approach for Frail Older People in Valencia (Spain): A Pre-Post Controlled Trial

Frailty is a common condition in older adults that negatively impacts health and quality of life. This study evaluated a comprehensive, personalised, and coordinated intervention under the value-based care approach to address frailty's multidimensional nature in older people in the primary care setting. It employed a pre-post randomised controlled design involving 242 frail individuals aged over 65 years living in the community in Valencia (Spain) between 2021 and 2023. Assessments were conducted at baseline, 12 months (immediately post-intervention), and 18 months. The intervention included a personalised care plan supported by technology, with monthly motivational follow-ups and plan updates by health professionals and participants. Outcomes were measured using an assessment questionnaire that included the International Consortium for Health Outcomes Measurement dataset for the older population: physical health, physical functioning, general mental health, satisfaction with social activities and relationships, ability to carry out usual social roles and activities, pain, general quality of life, loneliness, physical frailty, psychological frailty, and social frailty. The study found significant improvements in physical frailty, quality of life, reduced health resource use and hospitalisations and lower levels of pain and depression/anxiety compared to baseline. The findings suggest further research into value-based care approaches, emphasizing the development and activation of personalised, comprehensive programs for older individuals with frailty.

Assessment of the relation between depression, frailty, nutrition and quality of life among older adults: findings from a cross-sectional study in Greece

BACKGROUND

Quality of life (QOL) among older adults is a crucial aspect of geriatric care, particularly in the context of global demographic shifts toward ageing societies. Understanding the determinants of QOL in older adults is essential for developing effective interventions to promote well-being in this population.

METHODS

This cross-sectional study conducted in Greece aimed to investigate the complex relationship between depression, frailty, nutritional status, and QOL on 90 older adults (aged ≤65). Assessment instruments including the World Health Organization Quality of Life (WHOQoL)-BREF questionnaire, Geriatric Depression Scale (GDS), Clinical Frailty Scale (CFS), and Mini Nutritional Assessment (MNA) were utilised to evaluate various dimensions of QOL, depressive symptoms, frailty, and nutritional status.

RESULTS

The study revealed significant negative correlations between depression and frailty with all domains of QOL (P < 0.05), indicating that higher levels of depressive symptoms and frailty were associated with lower QOL across physical, psychological, social, and environmental dimensions. Conversely, positive correlations were found between nutritional status and all QOL domains (P < 0.05), suggesting that better nutritional status was linked to higher QOL. Multivariate logistic regression analysis further demonstrated associations between nutritional status and participant characteristics, with females being more likely to be malnourished (odds ratio (OR) = 6.56, P = 0.013), while better health status (OR = 0.34, P = 0.486) and marital status (OR = 0.02, P = 0.019) were protective against malnutrition.

CONCLUSION

These findings underscore the interconnectedness of depression, frailty, and nutritional status in shaping QOL among individuals. Holistic interventions targeting mental health, physical vulnerability, and nutritional well-being are essential for promoting overall well-being and functional outcomes in this population.

Causal relationship between neuroticism and frailty: A bidirectional Mendelian randomization study

BACKGROUND

Observational studies have shown that neuroticism is associated with frailty, but the causal relationship between them remains unclear.

METHODS

A two-sample Mendelian randomization (MR) study was conducted to explore the bidirectional causal relationship between neuroticism (n = 380,506 for the primary analysis, n = 79,004 for the validation) and frailty (n = 175,226) using publicly available genome-wide association study data. The inverse variance weighted (IVW), weighted median, and MR-Egger were used to obtain the causal estimates. Findings were verified through extensive sensitivity analyses and validated using another dataset. Multivariable MR (MVMR) analysis was performed to estimate the direct causal effects with adjustment of potential confounders. Two-step MR technique was then conducted to explore the mediators in the causal effects of neuroticism on frailty.

RESULTS

Genetically-predicted higher neuroticism score was significantly correlated with higher frailty index (IVW beta: 0.53, 95%CI: 0.48 to 0.59, P = 9.3E-83), and genetically-determined higher frailty index was significantly associated with higher neuroticism score (IVW beta: 0.28, 95%CI: 0.21 to 0.35, P = 1.3E-16). These results remained robust across sensitivity analyses and were reproducible using another dataset. The MVMR analysis indicated that the causal relationships remained significant after adjusting for the potential confounding factors. Mediation analysis revealed that depression, years of schooling, and smoking were significantly mediated the causal effects of neuroticism on frailty.

CONCLUSIONS

A bidirectional causal relationship existed between neuroticism and frailty. Our findings suggested that early intervention and behavioral changes might be helpful to reduce the neuroticism levels and prevent the development of frailty.

End-of-Life Care during the COVID-19 Pandemic: Decreased Hospitalization of Nursing Home Residents at the End of Life

(1) Background: Nursing homes (NHs) face unique challenges in end-of-life care for their residents. High rates of hospitalization at the end of life are frequent, often for preventable conditions. The increased clinical uncertainty during the pandemic, the high symptom burden of the COVID-19 disease, and the challenges in communication with families and between care teams might impact the option to hospitalize NH residents at the end of life. (2) Materials and methods: The study covered a 3-year period and compared the hospitalization rates of the NH residents of a sample of Portuguese NH during the last year of life before and during the pandemic. A total of 387 deceased residents were included in the study. (3) Results: There were fewer hospitalizations in the last year of life during the pandemic period, although the proportion of deaths at hospitals was the same. Hospitalizations occurred closer to death, and with more serious clinical states. The lower rate of hospitalization was due to lower hospitalization due to infection; (4) Conclusions: The data suggest an improvement in end-of-life care practices during the pandemic period, with the decrease in hospitalizations being due to potentially burdensome hospitalizations. The importance of the role of physicians, nurses, and caregivers in this setting may be relatively independent of each other, and each may be targeted in end-of-life care training. Further study is recommended to clarify the implications of the results and if the changes can be sustained in the long term.

The association between frailty biomarkers and 20-year all-cause and cardiovascular mortality among community-dwelling older adults

OBJECTIVES

While several biomarkers were previously associated with frailty and mortality, data are still contradicting. We aimed to evaluate the association between novel biomarkers and frailty among community-dwelling older adults to enhance understanding of the pathophysiology of frailty.

METHODS

Nine hundred and sixty-three older adults were screened during the third phase (1999-2008) of the Israel study on Glucose Intolerance, Obesity, and Hypertension (GOH). Frailty was defined as sedentary individuals, past 10 years hospitalizations, or at least one of the following: body mass index (BMI) <21 kg/m2; albumin <3.2 g/dl; ≥2 major baseline diseases. Biomarkers were evaluated for their association with frailty, all-cause, and cardiovascular mortality.

RESULTS

Mean baseline age was 72 ± 7 years, 471 (49%) were women, and 195 (20%) were classified as frail. Median follow-up for cardiovascular and all-cause mortality was 11 and 13 years, with 179 (18.6%) and 466 (48.4%) deaths recorded, respectively. Multivariable logistic regression showed greater odds for frailty with lower quartile of alanine aminotransferase (ALT) (OR = 1.8, 95%CI: 1.2-2.8, p = 0.01), and for each 5 µmol/L increment in homocysteine levels (OR = 1.3, 95%CI: 1.1-1.5, p = 0.001). Multivariate Cox regression showed greater all-cause and cardiovascular mortality risk for individuals with low ALT (HR = 1.6, 95%CI: 1.3-2.0, p < 0.001 and HR = 1.5, 95% CI: 1.0-2.2, p = 0.03, respectively), and high homocysteine (HR = 1.1, 95%CI: 1.1-1.3, p = 0.003 and HR = 1.2, 95%CI: 1.0-1.3, p = 0.04, respectively). Homocysteine association with mortality was more pronounced in those with baseline ischemic heart disease (IHD) compared with subjects free of IHD (P for interaction = 0.01).

CONCLUSIONS

Lower ALT and higher homocysteine were associated with frailty, all-cause and cardiovascular mortality. These available and low-cost biomarkers underscore the nutritional and metabolic aspects of frailty when screening high-risk older adults, especially those with IHD, and may be considered as preferable screening biomarkers to be tested among these individuals for frailty and mortality risk.

Real-world evidence evaluation of LDL-C in hospitalized patients: a population-based observational study in the timeframe 2021-2022

AIMS

European registries and retrospective cohort studies have highlighted the failure to achieve low-density lipoprotein-cholesterol (LDL-C) targets in many very high-risk patients. Hospitalized patients are often frail, and frailty is associated with all-cause and cardiovascular mortality. The aim of this study is to evaluate LDL-C levels in a real-world inpatient setting, identifying cardiovascular risk categories and highlighting treatment gaps in the implementation of LDL-C management.

METHODS

This retrospective, observational study included all adult patients admitted to an Italian hospital between 2021 and 2022 with available LDL-C values during hospitalization. Disease-related real-world data were collected from Hospital Information System using automated data extraction strategies and through the implementation of a patient-centered data repository (the Dyslipidemia Data Mart). We performed assessment of cardiovascular risk profiles, LDL-C target achievement according to the 2019 ESC/EAS guidelines, and use of lipid-lowering therapies (LLT).

RESULTS

13,834 patients were included: 17.15%, 13.72%, 16.82% and 49.76% were low (L), moderate (M), high (H) and very high-risk (VH) patients, respectively. The percentage of on-target patients was progressively lower towards the worst categories (78.79% in L, 58.38% in M, 33.3% in H and 21.37% in VH). Among LLT treated patients, 28.48% were on-target in VH category, 47.60% in H, 69.12% in M and 68.47% in L. We also analyzed the impact of monotherapies and combination therapies on target achievement.

CONCLUSIONS

We found relevant gaps in LDL-C management in the population of inpatients, especially in the VH category. Future efforts should be aimed at reducing cardiovascular risk in these subjects.

The independent and combined effects of physical activity and depressive symptoms on frailty in community-dwelling older adults: A cross-sectional study

AIMS

To investigate the independent and combined effects of physical activity (PA) and depressive symptoms on the risk of frailty in community-dwelling older adults.

BACKGROUND

Older adults face a high risk of frailty which is commonly used to predict adverse health outcomes in older patients. Engaging in PA and without depressive symptoms are crucial factors to prevent frailty. It is essential to investigate the independent and combined effects of these two variables on the risk of frailty.

METHODS

We included 3392 community-dwelling older adults. The FRAIL Scale was used to assess older adults' frail status (robust, prefrail and frail). Multiple logistic regression was utilized to examine the independent and combined effects of PA and depressive symptoms on the risk of prefrailty and frailty. The combined effects were visualized by marginal plots.

RESULTS

The prevalence of prefrailty and frailty in older adults were 42.16% and 10.58%. Compared with the group of "Light physical activity and With depressive symptoms", "Vigorous physical activity and Without depressive symptoms" had the lowest risk of prefrailty and frailty.

CONCLUSIONS

Older adults who do not engage in PA or have depressive symptoms increased the risk of frailty, but older adults with depressive symptoms could lower the risk of frailty through PA.

RELEVANCE TO CLINICAL PRACTICE

It is effective to reduce the risk of frailty by directing older adults to do moderate physical activity, although they have depressive symptoms. The focus should also be on older adults with depressive symptoms, who have at least more than twice and fourfold risk of prefrailty and frailty compared to those without.

IMPACT

This study offers insights for future interventions aimed at preventing frailty in older adults.

REPORTING METHOD

This study adhered to the STROBE checklist.

PATIENT OR PUBLIC CONTRIBUTIONS

Older adults participated in this study and completed questionnaires.

Prevalence, clinical characteristics, and long-term outcomes of new diabetes diagnosis in elderly patients undergoing percutaneous coronary intervention

Previous studies have reported associations between newly diagnosed diabetes and poor outcomes after percutaneous coronary intervention (PCI), but there is limited data focusing on elderly patients (age ≥ 65). This study aimed to analyze the prevalence and clinical implications of newly diagnosed diabetes in elderly patients who underwent PCI. From 2004 to 2021, a total of 2456 elderly patients who underwent invasive PCI at Korea University Guro Hospital were prospectively enrolled and followed up for a median of five years. The primary endpoint was five-year major adverse cardiovascular events (MACE). Cox regression was used to evaluate whether newly diagnosed diabetes impacted on long-term clinical outcomes. Newly diagnosed diabetes was presented in approximately 8.1% to 10.9% of elderly patients who underwent PCI. Those who had a new diagnosis of diabetes had a higher risk of MACE than previously known diabetes (25.28% vs. 19.15%, p = 0.039). After adjusting for significant factors, newly diagnosed diabetes remained an independent predictor of MACE (HR [hazard ratio] 1.64, 95% confidence interval [CI] 1.24-2.17, p < 0.001), cardiac death (HR 2.15, 95% CI 1.29-3.59, p = 0.003) and repeat revascularization (HR 1.52, 95% CI 1.09-2.11, p = 0.013), but not for non-fatal myocardial infarction (HR 1.66, 95% CI 0.94-2.12, p = 0.081). Newly diagnosed diabetes was associated with an increased risk of 5-year MACE compared with non-diabetes and previously diagnosed diabetes in elderly patients underwent PCI. More attention should be given to those elderly newly diagnosed diabetes population.

Pre-Frailty and Frailty in Hospitalized Older Adults: A Comparison Study in People with and without a History of Cancer in an Acute Medical Unit

A prospective observational study was conducted in a cohort of older adults ≥65 years (n = 329), admitted to the acute medical unit (AMU) of a tertiary hospital, to describe and compare characteristics including frailty status and clinical outcomes. Multivariable models compared older adults with and without a history of cancer to determine characteristics associated with frailty and pre-frailty. An adjusted Poisson regression model was used to compare the length of hospital stay (LOS) between the two groups. About one-fifth (22%) of the cohort had a history of cancer. The most common cancer types were prostate (n = 20), breast (n = 13), lung (n = 8) and gastrointestinal (n = 8). There was no difference in the prevalence of pre-frailty/frailty among patients with or without a history of cancer (58% vs. 57%, p > 0.05). Pre-frailty/frailty was associated with polypharmacy (OR 8.26, 95% CI: 1.74 to 39.2) and malnutrition (OR 8.91, 95% CI: 2.15 to 36.9) in patients with a history of cancer. Adjusted analysis revealed that the risk of having a longer LOS was 24% higher in older adults with a history of cancer than those without (IRR 1.24, 95% CI 1.10 to 1.41, p < 0.001). Clinicians in the AMU should be aware that older adults with a history of cancer have a higher risk of a longer LOS compared to those without.

Bidirectional causal relational between frailty and mental illness: a two-sample Mendelian randomization study

Background

Frailty has been associated with mental illness (MI) observational studies, but the causal relationship between these factors remains uncertain. We aimed to assess the bidirectional causality between frailty and MI by two-sample Mendelian randomization (MR) analyses.

Methods

To investigate the causal relationship among them, summary statistics of frailty index (FI) and six types of MI: anxiety, depression, affective disorder, mania, schizophrenia, and obsessive-compulsive disorder (OCD) were included in this MR study. This MR analysis was performed using inverse variance weighting (IVW), MR-Egger regression, and weighted median. The stability of the results was evaluated using Cochran's Q test, MR-Egger intercept test, Funnel Plots, and leave-one-out analysis.

Results

Genetic predisposition to FI was significantly associated with increased anxiety (odds ratio [OR] = 1.62, 95% confidence interval [CI] 1.13-2.33, P = 8.18E-03), depression (OR = 1.88, 95% CI 1.30-2.71, P = 8.21E-04), affective disorder (OR = 1.70, 95% CI 1.28-2.27, P = 2.57E-04). However, our study findings do not demonstrate a causal relationship between FI and mania (OR = 1.02, 95% CI 0.99-1.06, P = 2.20E-01), schizophrenia (OR = 1.02, 95% CI 0.07-0.86, P = 9.28E-01). In particular, although the IVW results suggest a potential causal relationship between FI and OCD (OR = 0.64, 95% CI 0.07-0.86, P = 2.85E-02), the directions obtained from the three methods we employed ultimately show inconsistency. Therefore, the result must be interpreted with caution. The results of the reverse MR analysis indicated a statistically significant and causal relationship between anxiety (OR = 1.06, 95% CI 1.01-1.11, P = 2.00E-02), depression (OR = 1.14, 95% CI 1.04-1.26, P = 7.99E-03), affective disorder (OR = 1.15, 95% CI 1.09-1.21, P = 3.39E-07), and schizophrenia (OR = 1.02, 95% CI 1.01-1.04, P = 1.70E-03) with FI. However, our findings do not provide support for a link between mania (OR = 1.46, 95% CI 0.79-2.72, P = 2.27E-01), OCD (OR = 1.01, 95% CI 1.00-1.02, P = 2.11E-01) and an increased risk of FI.

Conclusion

The MR results suggest a potential bidirectional causal relationship between FI and anxiety, depression, and affective disorder. Schizophrenia was found to be associated with a higher risk of FI. The evidence was insufficient to support a causal relationship between Fl and other Ml. These findings offer new insights into the development of effective management strategies for frailty and MI.

Association between modified frailty index and postoperative delirium in patients after cardiac surgery: A cohort study of 2080 older adults

AIM

To evaluate the association between frailty and postoperative delirium (POD) in elderly cardiac surgery patients.

METHODS

A retrospective study was conducted of older patients admitted to the intensive care unit after cardiac surgery at a tertiary academic medical center in Boston from 2008 to 2019. Frailty was measured using the Modified Frailty Index (MFI), which categorized patients into frail (MFI ≥3) and non-frail (MFI = 0-2) groups. Delirium was identified using the confusion assessment method for the intensive care unit and nursing notes. Logistic regression models were used to examine the association between frailty and POD, and odds ratios (OR) with 95% confidence intervals (CI) were calculated.

RESULTS

Of the 2080 patients included (median age approximately 74 years, 30.9% female), 614 were frail and 1466 were non-frail. The incidence of delirium was significantly higher in the frail group (29.2% vs. 16.4%, p < 0.05). After adjustment for age, sex, race, marital status, Acute Physiology Score III (APSIII), sequential organ failure assessment (SOFA), albumin, creatinine, hemoglobin, white blood cell count, type of surgery, alcohol use, smoking, cerebrovascular disease, use of benzodiazepines, and mechanical ventilation, multivariate logistic regression indicated a significantly increased risk of delirium in frail patients (adjusted OR: 1.61, 95% CI: 1.23-2.10, p < 0.001, E-value: 1.85).

CONCLUSIONS

Frailty is an independent risk factor for POD in older patients after cardiac surgery. Further research should focus on frailty assessment and tailored interventions to improve outcomes.

The impact of frailty on short-term prognosis in discharged adult stroke patients: A multicenter prospective cohort study

BACKGROUND

Frailty is commonly observed in stroke patients and it is associated with adverse outcomes. However, there remains a gap in longitudinal studies investigating the causal relationship between baseline frailty and short-term prognosis in discharged adult stroke patients.

OBJECTIVE

To examine the causal impact of frailty on non-elective readmission and major adverse cardiac and cerebral events, and investigate its associations with cognitive impairment and post-stroke disability.

DESIGN

A multicenter prospective cohort study.

SETTING

Two tertiary hospitals in Central and Northwest China.

PARTICIPANTS

667 adult stroke patients in stroke units were included from January 2022 to June 2022.

METHODS

Baseline frailty was assessed by the Frailty Scale. Custom-designed questions were utilized to assess non-elective readmission and major adverse cardiac and cerebral events as primary outcomes. Cognitive impairment, assessed using the Mini-Mental State Examination Scale (MMSE), and post-stroke disability, measured with the Modified Rankin Scale (mRS), were considered secondary outcomes at a 3-month follow-up. The impact of baseline frailty on non-elective readmission and major adverse cardiac and cerebral events was examined using bivariate and multiple Cox regression analyses. Furthermore, associations between baseline frailty and cognitive impairment, or post-stroke disability, were investigated through generalized linear models.

RESULTS

A total of 5 participants died, 12 had major adverse cardiac and cerebral events, and 57 had non-selective readmission among 667 adult stroke patients. Frailty was an independent risk factor for non-selective readmission (hazard ratio [HR]: 2.71, 95 % confidence interval [CI]: 1.59, 4.62) and major adverse cardiac and cerebral events (HR: 3.77, 95 % CI: 1.07, 13.22) for stroke patients. Baseline frailty was correlated with cognitive impairment (regression coefficient [β]: -2.68, 95 % CI: -3.78, -1.58) adjusting for socio-demographic and clinical factors and follow-up interval. However, the relationship between frailty and cognitive impairment did not reach statistical significance when further adjusting for baseline MMSE (β: -0.39, 95 % CI: -1.43, 0.64). Moreover, baseline frailty was associated with post-stroke disability (β: 0.36, 95 % CI: 0.08, 0.65) adjusting for socio-demographic and clinical variables, follow-up interval, and baseline mRS.

CONCLUSIONS

The finding highlights the importance of assessing baseline frailty in discharged adult stroke patients, as it is significantly associated with non-elective readmission, major adverse cardiac and cerebral events, and post-stroke disability at 3 months. These results highlight the crucial role of screening and evaluating frailty status in improving short-term prognosis for adult stroke patients. Interventions should be developed to address baseline frailty and mitigate the short-term prognosis of stroke.

TWEETABLE ABSTRACT

Associations between information and communication technology use and frailty in community-dwelling old-old adults: results from the ILSA-J

OBJECTIVES

Frailty is a significant cause of adverse health events including long-term care and hospitalization. Although information and communication technology (ICT) has become an integral part of modern life, it remains unclear whether ICT use is associated with frailty.

DESIGN

A cross-sectional study (Integrated Longitudinal Studies on Aging in Japan, ILSA-J).

SETTING AND PARTICIPANTS

Aged 75 and older data from the ILSA-J in 2017 (n = 2893).

METHODS

ICT use was measured using the technology usage sub-items of the Japan Science and Technology Agency Index of Competence. Specifically, the use of mobile phones, ATMs, DVD players, and sending e-mails were rated as "yes" (able to do) or "no" (unable to do), with the first quintile (≤1 point) defined as ICT non-users. Frailty was assessed using the Japanese version of the Cardiovascular Health Study criteria based on the phenotype model (e.g., weight loss, slowness, weakness, exhaustion, and low activity). Further, multivariate logistic regression analysis analyzed its association with ICT use. Subgroup analyses were stratified according to gender, years of education, and living arrangements.

RESULTS

Higher ICT use was not associated with frailty after adjusting for covariates (odds ratio [OR]: 0.53; 95%CI 0.39-0.73). Similar associations were found in the sub-groups of women (OR 0.45, 95%CI 0.30-0.66), <13 years of education (OR 0.48, 95%CI 0.34-0.67), living alone (OR 0.46, 95%CI 0.27-0.79), and living together (OR 0.57, 95%CI 0.38-0.85). No association existed between using ICT and frailty in the sub-groups of men and ≥13 years of education.

CONCLUSIONS AND IMPLICATIONS

Higher ICT use is associated with the absence of frailty in individuals 75 years and older. Such benefits may be particularly pronounced in women, those with lower levels of education, and older adults living alone or with others.

Development and Evaluation of a Software Designed by a Nursing and Technology Team to Assess the Health Status of Adults over 65 Years of Age

Objective

This work sought to develop the Actuasalud platform as a useful tool for nursing that permits assessing health, in term of frailty, in population over 65 years of age.

Methods

For the design and development of Actuasalud, two working groups were formed: one from nursing with different profiles, to identify the scientific content and a computer science group responsible for the software programming and development. Both teams adapted the scientific content to the technology so that the tool would allow for population screening with detection of health problems and frailty states.

Results

The software was developed in three large blocks that include all the dimensions of frailty: a: sociodemographic variables, b: comorbidities, and c: assessment tools of autonomy-related needs that evaluate the dimensions of frailty. At the end of the evaluation, a detailed report is displayed through bar diagram with the diagnosis of each of the dimensions assessed. The assessment in the participating elderly showed that 44.7% (n = 38) of the population was considered not frail, and 55.3%; (n = 47) as frail. Regarding associated pathologies, high blood pressure (67.1%; n = 57), osteoarthritis and/or arthritis (55.3%; n = 47), diabetes (48.2%; n = 41) and falls during the last year (35.3%; n = 30) were highlighted.

Conclusion

Actuasalud is an application that allows nursing professionals to evaluate frailty and issue a quick diagnosis with ordered sequence, which helps to provide individualized care to elderly individuals according to the problems detected during the evaluation.

Regional variation in prevalence of frailty in India: Evidence from longitudinal ageing study in India (LASI) wave-1

Background & objectives Frailty is a geriatric syndrome with clinical and public health implications. It represents the state of increased vulnerability. This study aimed to estimate the prevalence of frailty and pre-frailty by demographic characteristics and geographical regions in India. Furthermore, it also aimed to examine the association of this prevalence with selected health outcomes using data from the Longitudinal Ageing Study of India (LASI). Methods This is a secondary analysis of LASI wave-1 data. A total of 26,058 respondents aged ≥60 yr were included for analysis. Frailty was assessed using Fried's frailty phenotype, including slowness, shrinking, low physical activity, weakness, and low endurance. Descriptive statistics were used to study frailty distribution. The odds ratio (OR) of health events across the frailty categories was computed using ordinal logistic regression. Results The findings of this study suggest that the prevalence of frailty and pre-frailty was 29.2 and 58.8 per cent, respectively. The prevalence of frailty was higher among women (37.3%), illiterate (37%) and rural residents (31%). It ranged between 14.5 per cent in Uttarakhand and 41.3 per cent in Arunachal Pradesh. Frailty was strongly associated with depression [OR: 2.09, Confidence Interval (CI): 1.98-2.21] and activities of daily living (ADL) difficulty (OR: 1.75, CI: 1.64-1.86). Higher odds were reported for fracture (OR: 1.24, CI: 1.01-1.51) and multimorbidity (OR: 1.18, CI: 1.04-1.33) among frailty. Interpretation & conclusions The heterogeneity of frailty prevalence across States indicates the need for population-specific strategies. A sharp age-related increase in prevalence highlights the need for preventive measures. Furthermore, the high prevalence of frailty among women, illiterate and rural residents indicates the target population for receiving preventive interventions. Lastly, a heterogeneity in frailty prevalence across different States indicates the scope for region-specific programmes.

Effects of androgen deprivation therapy on elderly men with high-risk prostate cancer: PROSARC observational study

INTRODUCTION

Prostatic carcinoma (PC) is a frequent neoplasm in elderly patients. Although androgen deprivation is associated with survival benefits, it is also related to adverse effects such as osteoporosis, frailty, or sarcopenia, which can negatively affect the patient's quality of life. This study aims to quantify and evaluate the prevalence of osteoporosis, frailty, or sarcopenia in elderly PC patients before and after androgen deprivation. We present data from an interim analysis.

MATERIALS AND METHODS

PROSARC is a national (Spain) prospective observational study (May-2022-May-2025) still in progress in 2 hospitals. It includes patients with high-risk PC, aged ≥70 years, non-candidates for local treatment and scheduled to start androgen deprivation therapy. The following variables are analyzed: comorbidity, frailty (Fried frailty phenotype criteria), osteoporosis, sarcopenia (EWGSOP2), fat mass and muscle mass, before treatment and after 6 months of follow-up.

RESULTS

A 6-month follow-up was completed by 12/25 included patients (mean age, 84 years), with a high baseline prevalence of pre-frailty/frailty (67.7%), sarcopenia (66.7%) and osteoporosis (25%). Treatment did not significantly alter these variables or comorbidity. We observed changes in body mass index (p=0.666), decreased mean value of appendicular muscle mass (p=0.01) and increased percentage of fat mass (p=0.012).

CONCLUSION

In patients with high-risk PC, advanced age and a considerable prevalence of osteoporosis, frailty and sarcopenia, androgen deprivation (ADT; 6 months) produces decreased muscle mass without impact on the incidence of the known adverse effects of androgen deprivation.

Factors Associated with Frailty in Older Adults in Community and Nursing Home Settings: A Systematic Review with a Meta-Analysis

Background: Frailty is a globally recognized issue. However, there is a lack of evidence exploring factors associated with frailty among older residents in community and nursing-home settings. Methods: To explore the prevalence and factors associated with frailty among older adults in community and nursing-home settings, we conducted a systematic search following the PRISMA guidelines across Web of Science, MEDLINE, EMBASE, PubMed, and Cochrane databases up until January 2024, selecting 38 studies which encompassed 150,642 participants. Results: Our findings showed higher frailty prevalence in nursing homes compared to communities. Frailty was significantly associated with sociodemographic (living alone, poor self-reported health), physiological (poor sleep, low activity of daily living), behavioral (physical inactivity) and disease (chronic conditions, depression) factors in both community and nursing-home settings. Conclusions: There are numerous factors associated with frailty in older adults in nursing-home and community settings. These factors underscore the significance of promptly identifying high-risk individuals and devising appropriate interventions to mitigate frailty among them.

Which Comprehensive Geriatric Assessment (CGA) instruments are currently used in Germany: a survey

BACKGROUND

The Comprehensive Geriatric Assessment (CGA) records geriatric syndromes in a standardized manner, allowing individualized treatment tailored to the patient's needs and resources. Its use has shown a beneficial effect on the functional outcome and survival of geriatric patients. A recently published German S1 guideline for level 2 CGA provides recommendations for the use of a broad variety of different assessment instruments for each geriatric syndrome. However, the actual use of assessment instruments in routine geriatric clinical practice and its consistency with the guideline and the current state of literature has not been investigated to date.

METHODS

An online survey was developed by an expert group of geriatricians and sent to all licenced geriatricians (n = 569) within Germany. The survey included the following geriatric syndromes: motor function and self-help capability, cognition, depression, pain, dysphagia and nutrition, social status and comorbidity, pressure ulcers, language and speech, delirium, and frailty. Respondents were asked to report which geriatric assessment instruments are used to assess the respective syndromes.

RESULTS

A total of 122 clinicians participated in the survey (response rate: 21%); after data cleaning, 76 data sets remained for analysis. All participants regularly used assessment instruments in the following categories: motor function, self-help capability, cognition, depression, and pain. The most frequently used instruments in these categories were the Timed Up and Go (TUG), the Barthel Index (BI), the Mini Mental State Examination (MMSE), the Geriatric Depression Scale (GDS), and the Visual Analogue Scale (VAS). Limited or heterogenous assessments are used in the following categories: delirium, frailty and social status.

CONCLUSIONS

Our results show that the assessment of motor function, self-help capability, cognition, depression, pain, and dysphagia and nutrition is consistent with the recommendations of the S1 guideline for level 2 CGA. Instruments recommended for more frequent use include the Short Physical Performance Battery (SPPB), the Montreal Cognitive Assessment (MoCA), and the WHO-5 (depression). There is a particular need for standardized assessment of delirium, frailty and social status. The harmonization of assessment instruments throughout geriatric departments shall enable more effective treatment and prevention of age-related diseases and syndromes.

Efficacy of deprescribing on health outcomes: An umbrella review of systematic reviews with meta-analysis of randomized controlled trials

BACKGROUND

Deprescribing is an important intervention across different settings in medicine, but the literature supporting such a practice is still conflicting. Therefore, we aimed to capture the breadth of outcomes reported and assess the strength of evidence of the use of deprescribing for health outcomes.

METHODS

Umbrella review of systematic reviews of the use of deprescribing searching in Medline, Scopus, and Web of Science until 01 November 2023. The grading of evidence was carried out using the GRADE for intervention studies, whilst data regarding systematic reviews were reported as narrative findings.

RESULTS

Among 456 papers, 12 systematic reviews (six with meta-analysis) for a total of 231 RCTs and 44,193 patients were included. In any setting, deprescribing was able to significantly reduce the number of total and of potentially inappropriate medications (PIMs) in older patients (low certainty of evidence) and to reduce the proportion of participants potentially having several or PIMs (moderate certainty of evidence). In community, supported by a high certainty of evidence, deprescribing was not more effective than standard care in decreasing injurious falls, any falls or number of fallers. In nursing home, deprescribing was associated with a significantly lower PIMs than standard care (very low certainty of evidence). In end-of-life situations, deprescribing significantly reduced mortality rate of approximately 41% (high certainty of evidence).

CONCLUSIONS

Deprescribing is a promising intervention across different settings and situations, but a notable gap in the literature concerning its effects on substantial outcomes still exists.

Interaction between hypertension and frailty and their impact on death risk in older adults: a follow-up study

BACKGROUND

Hypertension and frailty often occur concurrently, exhibiting increasing prevalence in the older population. In this study, we analyzed the frailty status among older adults with hypertension and the impact of their interaction on death risk.

METHOD

This prospective cohort survey study included data from older people in an urban community in Beijing collected between 2009 and 2020 using the cluster random sampling method. The participants were older adults who were ≥ 60 years old at the time of investigation and had lived at the place of investigation for > 1 year. The survey variables comprised those related to health and frailty status assessed during the 2009 baseline survey, along with death-related information as outcome variables in 2020. Additionally, a frailty index (FI) model was used to examine the frailty status among the older adults at baseline. The effects of hypertension prevalence on the age-related frailty changes as well as on mortality for varying degrees of frailty were further analyzed. Lastly, Cox regression and Kaplan-Meier curves were applied to evaluate the impact of the interaction between hypertension and frailty on death risk.

RESULTS

Ultimately, 1197 older individuals aged between 60 and 101 years(average age at baseline: 74.8 ± 8.6 years) were included .Among them, 475 individuals were men (mean age:74.8 ± 8.8 years), and 722 were women (mean age:74.8 ± 8.4 years).Frailty was identified in 151 individuals, leading to a prevalence rate of 12.6%(151/1197),while hypertension was detected in 593 (prevalence rate:49.5% [593/1197]).A total of 443 deaths were recorded by 2020, resulting in a mortality rate of 37.0% (443/1197).Moreover, FI values and mortality rates were higher at any age in older adults with hypertension compared with those without hypertension. Survival time analysis showed that the median survival time of older adults with hypertension and frailty was the shortest (39.0[95%CI: 35.6-42.3] months)when compared with that of older adults without hypertension but with frailty (52.9 [95%CI: 46.6-59.3] months), those with hypertension but without frailty (102.7 [95%CI: 98.7-106.8] months), and those without hypertension and frailty (127.9 [95%CI: 113.5-134.7] months),with log-rank x2 = 999.686 and P < 0.001. Furthermore, Cox regression results demonstrated that older adults with hypertension and frailty had the highest death risk when compared with that of older adults without hypertension and frailty (HR = 1.792, P < 0.001), those without hypertension but with frailty (HR = 1.484, P < 0.001), and those with hypertension but without frailty (HR = 1.406, P = 0.005).

CONCLUSION

Frailty is prevalent among older adults with hypertension; however, older adults with both hypertension and frailty have a relatively higher mortality risk. Therefore, screening and assessment of frailty in the older population with hypertension are crucial for its early identification, thereby enabling timely and appropriate interventions to prevent or delay the adverse effects of this concurrent condition.

Multimorbidity and frailty are associated with poorer SARS-CoV-2-related outcomes: systematic review of population-based studies

BACKGROUND

Estimating the risks and impacts of COVID-19 for different health groups at the population level is essential for orienting public health measures. Adopting a population-based approach, we conducted a systematic review to explore: (1) the etiological role of multimorbidity and frailty in developing SARS-CoV-2 infection and COVID-19-related short-term outcomes; and (2) the prognostic role of multimorbidity and frailty in developing short- and long-term outcomes. This review presents the state of the evidence in the early years of the pandemic. It was conducted within the European Union Horizon 2020 program (No: 101018317); Prospero registration: CRD42021249444.

METHODS

PubMed, Embase, World Health Organisation COVID-19 Global literature on coronavirus disease, and PsycINFO were searched between January 2020 and 7 April 2021 for multimorbidity and 1 February 2022 for frailty. Quantitative peer-reviewed studies published in English with population-representative samples and validated multimorbidity and frailty tools were considered.

RESULTS

Overall, 9,701 records were screened by title/abstract and 267 with full text. Finally, 14 studies were retained for multimorbidity (etiological role, n = 2; prognostic, n = 13) and 5 for frailty (etiological role, n = 2; prognostic, n = 4). Only short-term outcomes, mainly mortality, were identified. An elevated likelihood of poorer outcomes was associated with an increasing number of diseases, a higher Charlson Comorbidity Index, different disease combinations, and an increasing frailty level.

DISCUSSION

Future studies, which include the effects of recent virus variants, repeated exposure and vaccination, will be useful for comparing the possible evolution of the associations observed in the earlier waves.

The relationship between dysphagia and frailty among Chinese hospitalized older patients: a serial mediation model through self-perceived oral health and self-reported nutritional status

BACKGROUND

Frailty contributes to adverse outcomes in older adults and places a heavy burden on healthcare resources. Dysphagia is associated with frailty, but the mechanisms by which dysphagia affects frailty in older adults are unclear. This study aimed to investigate a serial mediating effect of self-perceived oral health and self-reported nutritional status in the relationship between dysphagia and frailty among hospitalized older patients in China.

METHODS

This cross-sectional study included 1200 patients aged ≥ 65 years in the Department of Geriatrics, Shaanxi Provincial People's Hospital. A structured face-to-face interview was used to survey the following questionnaires: General Information Questionnaire, Tilburg Frailty Indicators (TFI), Eating Assessment Tool-10 (EAT-10), 30mL Water Swallow Test (WST), Geriatric Oral Health Assessment Index (GOHAI), and Short-Form Mini-Nutritional Assessment (MNA-SF). A total of 980 participants with complete data were included in the analysis. Statistical analysis was performed using SPSS 26.0 and Amos 28.0 software. Spearman's correlation analysis was used for correlation analysis of study variables. The results of the multivariate linear regression analysis for frailty were used as covariates in the mediation analysis, and the structural equation model (SEM) was used to analyze the mediating effects among the study variables.

RESULTS

Dysphagia, self-perceived oral health, self-reported nutritional status, and frailty were significantly correlated (P<0.001). Dysphagia was found to directly affect frailty (β = 0.161, 95%CI = 0.089 to 0.235) and through three significant mediation pathways: (1) the path through self-perceived oral health (β = 0.169, 95%CI = 0.120 to 0.221), accounting for 36.98% of the total effect; (2) the path through self-reported nutritional status (β = 0.050, 95%CI = 0.023 to 0.082), accounting for 10.94% of the total effect; (3) the path through self-perceived oral health and self-reported nutritional status (β = 0.077, 95%CI = 0.058 to 0.102), accounting for 16.85% of the total effect. The total mediation effect was 64.77%.

CONCLUSIONS

This study indicated that dysphagia was significantly associated with frailty. Self-perceived oral health and self-reported nutritional status were serial mediators of this relationship. Improving the oral health and nutritional status of hospitalized older patients may prevent or delay the frailty caused by dysphagia.

Frailty and Survivability of Polish Caucasian Nonagenarians and Centenarians

Frailty is a major geriatric problem leading to an increased risk of disability and death. Prevention, identification, and treatment of frailty are important challenges in gerontology and public health. The study aimed to estimate the prevalence of the frailty phenotype (FP) among the oldest-old Polish Caucasians and investigate the relationship between the FP and mortality. Baseline data were collected from 289 long-lived individuals, including 87 centenarians and 202 subjects aged 94-99. Mortality was obtained from population registers over the following 5 years. Sixty percent of subjects were classified as frail, 33% as prefrail, and 7% as robust. Frailty was more common in women than men and among centenarians than nonagenarians. During the 5-year observation period, 92.6% of the frail women and all frail men died, while mortality rates were lower among prefrail, 78.8% and 66.7%, and robust individuals, 60% and 54.5%, respectively. In the survival analysis, frailty was the strongest negative risk factor: HR = 0.328 (95% CI: 0.200-0.539). The inability to perform handgrip strength measurement was an additional predictor of short survival. In conclusion, the FP is prevalent in nonagenarians and centenarians and correlates with lower survivability. Future studies should address differences between unavoidable age-associated frailty and reversible disability in long-lived individuals.

Mediterranean diet associated with lower frailty risk: A large cohort study of 21,643 women admitted to hospitals

BACKGROUND

Mediterranean diet is traditionally considered as a healthy dietary pattern, while its association with frailty has not been confirmed. This study investigated associations between Mediterranean diet and risk of frailty among women admitted to hospitals in England from an older-aged women's cohort study.

METHODS

A modified Mediterranean diet was evaluated from a validated 217-item food frequency questionnaire. Incident frailty was determined using a hospital frailty risk score based on linkage to Hospital Episode Statistics up to March 2019. Cox proportional hazard models were conducted to estimate hazard ratios (HR) and 95% confidence intervals (CI). Further subgroup analyses stratified by age and body mass index (BMI), and sensitivity analyses were additionally explored.

RESULTS

Over a mean follow-up of 13 years, there were 14,838 (68.6%) cases of frailty out of 21,643 individuals included in this study. Compared with low adherence to Mediterranean diet, moderate adherence was associated with 5% (HR = 0.95, 95%CI: 0.91, 0.99) lower risk of frailty, with high adherence associated with even lower risk (HR = 0.89, 95%CI: 0.85, 0.94). The magnitude of above associations remained consistent in subgroups stratified by age and BMI, except the association between moderate adherence and risk of frailty was attenuated in the ≥60-year (HR = 0.99, 95%CI: 0.93, 1.06) and the BMI > 24.9 kg/m2 (HR = 0.97, 95%CI: 0.91, 1.03) subgroups.

CONCLUSIONS

Adherence to Mediterranean diet was associated with lower risk of frailty. The better the adherence, the greater the magnitude of the protective association. Older and overweight women may potentially benefit from greater adherence to the Mediterranean diet regarding frailty prevention.
